If you haven't decided on a Halloween costume yet, you’ve got just under a week to choose a look. And Pinterest is a great place to go for spooky beauty ideas. The only problem: There are more than 273 million Halloween makeup tutorials on the site. That's a lot of scrolling, but there's no need to freak out. Our friends at Pinterest helped us round up the top five ideas that are being pinned like crazy. The lineup is pretty diverse, from trendy movie characters to scary Halloween classics. And for some of these looks, all you need is a little eyeliner and lipstick for a complete transformation. So get ready to put that makeup palette to good use.

Harley Quinn from Suicide Squad

The villain-turned-hero’s gothic makeup is easy to recreate thanks to YouTube blogger MirandavanR's popular tutorial. It's been pinned thousands of times and The Suicide Squad comic got a movie redo this year, so this look is guaranteed to be a hit this year.

Glam Skeleton

Transforming your face into a skull is pretty easy using black face paint or eyeliner. San Francisco-based entrepreneur Nichole Ciotti grabbed a friend to create a ghoulish version of the Pinterest sensation.
